简单描述
型态特徵 | 形态测量图
背的软条 (总数): 10-11; 臀鳍软条: 25 - 33. Diagnosis: Distinguished from its congeners except A. saguazu and A. elachylepis by the presence of a second vertically elongate humeral spot (vs. one humeral spot). It differs from saguazu, elachylepis, and fasciatus species complex by the autapomorphic presence of a space between the dentary teeth, which are relatively slender, with cusps positioned close to one another, and by the presence of a maximum of five cusps in each dentary tooth (vs. maximum of 7 cusps). Differs from fasciatus, rutilus, and elachylepis by the presence of 2 - 5, usually 5, tricuspid teeth on the anterior margin of maxilla (vs. 1 - 2 teeth, usually 1, on anterior margin of maxilla) (Ref. 56653).
鉴别: 除了 A. saguazu 与 A. elachylepis 以外与它的同类区分藉由有第二个细长垂直的肩部斑点 (. vs. 一个肩部的斑点) 它有别于 saguazu ， elachylepis 与 fasciatus 复合种藉由 autapomorphic 有一个间隔的空间齿骨齿, 那是相当细长的, 由于尖头放置接近彼此, 而且藉由在每个齿骨牙齿中有五个尖头的极大.(vs.7个尖头的极大) 有别于 fasciatus ， rutilus 與 elachylepis 藉由有 2- 5, 通常 5, 在顎骨的前緣上的三尖齒 (vs.1- 2個齒, 通常 1, 在顎骨的前緣上).(參考文獻 56653)
